Technical ReportNetApp Deduplication for FAS and V-SeriesDeployment and Implementation GuideData ONTAP 7.x – 8.0.xCarlos Alvarez, NetAppFeb 2011 TR-3505 Version 8ABSTRACTThis technical report covers NetApp deduplication for FAS and V-Series running on DataONTAP versions 7.x – 8.0.x. For information on deduplication running on Data ONTAP 8.1and above see TR-3958 or for clustered Data ONTAP see TR-3966 for details.The report describes in detail how to implement and use deduplication and providesinformation on best practices, operational considerations, and troubleshooting.
